Fix Recommendation

If "difok" was not set at all in "/etc/pam.d/common-password-vmware.local" then run the following command:

# sed -i '/pam_cracklib.so/ s/$/ difok-8/' /etc/pam.d/common-password-vmware.local

If "difok" was set incorrectly, run the following command to set it to "8":

# sed -i '/pam_cracklib.so/ s/difok=./difok=8/' /etc/pam.d/common-password-vmware.local

Check Contents

Check that at least eight characters need to be changed between old and new passwords during a password change by running the following command:

# grep pam_cracklib /etc/pam.d/common-password-vmware.local

The "difok" parameter indicates how many characters must be different. The DoD requires at least eight characters to be different during a password change. This would appear as "difok=8".

If "difok" is not found or not set to at least "8", this is a finding.

Expected Result:
password requisite pam_cracklib.so dcredit=-1 ucredit=-1 lcredit=-1 ocredit=-1 minlen=14 difok=8 retry=3
